(a) A party or support enforcement agency seeking to enforce
a support order or an income withholding order, or both, issued in
another state or a foreign support order may send the documents
required for registering the order to a support enforcement agency
of this state.

(b) Upon receipt of the documents, the support enforcement
agency, without initially seeking to register the order, shall
consider and, if appropriate, use any administrative procedure
authorized by the law of this state to enforce a support order or
an income withholding order, or both. If the obligor does not
contest administrative enforcement, the order need not be
registered. If the obligor contests the validity or administrative
enforcement of the order, the support enforcement agency shall
register the order pursuant to this article.
